Parser cannot process 'allOf' correctly

[ronny-stauffer]

In an example I defined the schema for a data structure with a single property which has an enumeration type. I use the allOf keyword (as a wrapper construct) in order to be allowed to also specify a description for the property:

components:
  schemas:
    TestDTO:
      required:
        - choice
      type: object
      properties:
        choice:
          description: Choice description
          allOf:
            - $ref: '#/components/schemas/TestEnum'
    TestEnum:
      type: string
      enum:
        - One
        - Two
        - Three

I then use the Swagger Parser v3 to parse (and print afterwards) the above definition (embedded in a complete OpenAPI document).

        String apiDefinition;
        try (Reader apiDefinitionReader = new InputStreamReader(new ClassPathResource("test.yaml").getInputStream())) {
            apiDefinition = CharStreams.toString(apiDefinitionReader);
        }

        OpenAPIV3Parser parser = new OpenAPIV3Parser();
        ParseOptions options = new ParseOptions();
        options.setResolve(true);
        options.setResolveCombinators(true);
        options.setResolveFully(true);
        options.setFlatten(true);
        OpenAPI openAPI = parser.readContents(apiDefinition, /* auths: */ null, options).getOpenAPI();

        System.out.println(Yaml.mapper().writeValueAsString(openAPI));

The output is then as follows:

openapi: 3.0.1
info:
  title: Test
  description: Description
  version: "1"
servers:
- url: /
tags:
- name: Test
  description: Test tag description
paths:
  /do-something:
    post:
      tags:
      - Test
      description: Do something operation description
      operationId: do-something
      requestBody:
        content:
          application/json:
            schema:
              required:
              - choice
              type: object
              properties:
                choice: {}
      responses:
        "200":
          description: Do something operation result description
components:
  schemas:
    TestDTO:
      required:
      - choice
      type: object
      properties:
        choice: {}
    TestEnum:
      type: string
      enum:
      - One
      - Two
      - Three

It seems the the parser cannot process the allOf construct correctly.
